Queer theory is likely one of the most well-known and controversial recent schools of thought, and its impact has been felt in the academic world and beyond. It appeared in the early 1990s in the United States, as a direct offshoot of LGBT (lesbian, gay, bisexual, transgendered) collectives, the work of Foucault (in particular, his History of Sexuality and ideas such as “biopolitics”), and Derrida’s deconstructionism. This school of thought, while in no way a homogenous trend, is characterized by the questioning of the notion of gender and the idea that sexual identity and behaviour would be genetically determined. In this context, queer theory formulates the hypothesis that sexuality is actually a social construction. This presumes that sexuality is not biologically stamped on human nature, but rather takes on ever-changing social forms, wherein a given individual can live out one or many sexual identities. This hypothesis leads us to call into question social classifications from the fields of traditional psychology, philosophy, anthropology, and sociology, which tend to look at one measure at a time for classifying individuals (class, gender, etc.).
